Engineering companies have found in thermofusion systems a technique for pipe assembly, which has been gaining ground because of the large number of benefits it presents. It is a system that has important results of quality and an excellent relation of cost benefit in all type of installations. It allows an agile work, avoid the formation of tartar and corrosion, have a great durability and connections safer. The process is very simple: for a few seconds, the tube and the connection are heated to a temperature between 260 ° and 270 ° C, the heating time varies between 7 and 60 seconds depending on the diameter of the tube. After that time, the tube and the connection are joined by interposition of their ends, melting in one piece. That is why the installation of thermofusion networks remain ideal for many companies looking for quality, cleanliness, economy, and protect the environment at a reasonable cost
